Fires at base stations

Fires at base stations

A breakdown occurred on 11 September and continued until the next day in the departments of Tarn and Aveyron. The authorities said: "Following deliberate damage to two relay antennas, 52,000 Bouygues and SFR subscribers were affected by a loss of network".


The exact details of this failure were not communicated, but the authorities nevertheless made it clear that it was in no way accidental. Indeed, a relay antenna and a TDF pylon were set on fire in Albi.

These actions were also denounced by the Secretary of State for the Digital Economy, Cédric O, on Twitter: "I strongly condemn the arson of a TDF tower which affected the network of SFR and Bouygues Telecom subscribers, and the communications of 50,000 people in the Tarn and Aveyron."


This event takes place in a very particular context. For more than a year now, we have been witnessing arson attacks on 5G antennas throughout France and Europe. While the police are investigating, some do not hesitate to claim responsibility for their acts, as was the case with the anarchist movement, according to Ouest-France.

5G: more antennas to cover France

5G: more antennas to cover France

Published on February 4th, a Tactis study shows that in peri-urban areas, around 30% more sites will be needed to offer a 5G service level equivalent to 4G. This is particularly true in rural areas, where twice as many sites will be needed to provide equivalent coverage, and up to three times as many to deliver a broadband service.


To arrive at these estimates, Tactis experts have simulated 4G coverage in several peri-urban and rural areas from existing mobile antenna sites. They then simulated what 5G coverage would look like based on these same sites. In its projections, Tactis uses only the 3.5 GHz frequency band. However, it is clear that coverage is much less in 5G than in 4G.


Why such differences? Because the frequencies used to provide 5G will not be the same as for 4G, and they do not have the same characteristics. "Current 4G deployments use low frequencies, which carry far, while the high frequencies that will be used for 5G deployments, in the 3.5 GHz band, offer a lot of throughput but carry much less far," explains Julien Renard, radio expert at Tactis. However, the Tactis simulations do not include the 700 MHz frequency band, even though these frequencies are low and allow much better coverage of territories. To explain this choice, Julien Renard points out that the 700 MHz band will not allow us to benefit from "all the promises of 5G". It is impossible, he says, to offer a real broadband service with these frequencies.


The densification of 5G networks in the heart of cities and the most urbanized areas, which are generally very profitable for operators, will certainly be a priority for Orange, SFR, Bouygues Telecom and Free. On the other hand, the firm is looking at peri-urban areas and rural areas, which are less profitable. To acquire 3.5 GHz frequencies, operators will have to commit to ensuring that by 2024 and 2025, 25% of the number of 5G sites deployed will be in rural areas. However, there is no obligation to deploy new sites in rural areas. However, this will be an imperative for providing quality 5G coverage, according to Tactis.


The risk? A new digital divide between urban and rural areas. The latter could end up, in the long term, with non-existent or poor quality 5G networks. The solution to further densify the networks could come from a greater mutualisation of mobile infrastructures.

Operators are already thinking about this. In an interview with Les Echos, Stéphane Richard, CEO of Orange, judged that "the question of an advanced mutualization is raised. [...] Orange has signed (agreements in this sense) in Spain, Poland and Belgium. In France, some of our competitors already share their networks to a large extent; we are also thinking about it". The major manoeuvres could start as early as this year, once the 5G frequencies have been allocated.

Huawei: slowness of the French administration

Huawei: slowness of the French administration

According to several telecom specialists, operators' uncertainty about whether or not to use Huawei's 5G antennas for their new mobile networks is growing.


Yet the law on securing mobile networks (nicknamed "anti-Huawei") has made things clearer. Indeed, operators must get the green light from Anssi - the National Agency for Information Systems Security - before using 5G equipment. The Agency then has two months to study their files.

At the end of December, Orange, SFR and Bouygues Telecom all submitted authorization applications for the deployment of Chinese 5G antennas in France.


However, according to several sources, cyber-experts in the French-speaking part of the country are making more and more requests for further information. It's not serious, "says a concerned operator. If they're trying to save time this way, it's a mistake. A court would never agree with them, the case law is very clear".


What operators are actually afraid of is that the Anssi is deliberately dragging its feet to avoid having to post a denial of clearance ahead of the 5G frequency allocations, scheduled for April. If equipment manufacturers were to be denied to operators before that date, the latter would then be weakened and could therefore lower their bids for the 5G auctions .


According to the new legal framework, the absence of a positive response from the Anssi within two months is tantamount to a refusal. But this time limit runs from receipt of a complete file... a complete file. Hence the irritation of the operators in front of what one actor describes as "delaying tactics" to postpone the deadline.

A specialist in the sector even indicates that "Some operators are impatiently waiting for an implicit refusal to be able to take legal action".


But the strategic interest of the four players differs. Indeed, Free, using only antennae of the Finnish Nokia, is not concerned.

Orange does not use Huawei antennas in France to date. However, it wants to have the possibility to solicit the Chinese supplier for its future 5G network.

As for SFR and Bouygues Telecom, which use Huawei on half of their respective networks, they are keen to be able to continue doing business with the Shenzhen giant. Doing without its 5G antennas would indeed require dismantling the 3G and 4G antennas for compatibility reasons. The cost would be enormous. You would have to buy and install this equipment. Above all, a large part of the network would be disrupted for many months, pushing customers into the arms of the competition. "Free would become, without doing anything, the second best network in the country... while it remains far behind" as a telecom specialist analyses.
